The top plate 74 a of the holder 56 is provided with clamp mechanisms 76 and 77 that clamp the recording media 36 and 46 from the left and right sides, and a media insertion detection switch 78. A guide rail 79 is attached to the lower surface of the top plate 14a of the cover 14 to guide the insertion of the emergency tool.
[0034]
The second sliding member 75 attached to the inside of the sliding member 74 includes a top plate 75a that is in close contact with the lower surface of the top plate 74a, and side plates 75b and 75c that are bent downward inside the guide members 58 and 59. Have On the inner walls of the side plates 75b and 75c, the guide portions 75d and 75e fitted in the guide grooves 42 and 52 of the recording media 36 and 46 and the contact portions where the insertion side end portions 36a and 46a of the recording media 36 and 46 abut. (Not shown) protrudes.
[0035]
Further, the guide walls 58a and 59a of the guide members 58 and 59 are inserted into gaps formed between the side plates 74b and 74c and the side plates 75b and 75c, thereby allowing the holder 56 to slide in the A and B directions. To guide.
[0036]
Here, the configuration of the clamp mechanisms 76 and 77 will be described.
The clamp mechanisms 76 and 77 are configured to press and hold both sides of the recording media 36 and 46 by the insertion operation of the recording media 36 and 46 inserted into the holder 56, and are slidable on the top plate 74a. The slide members 80 and 81 are attached, and torsion springs 82 and 83 that urge the slide members 80 and 81 outward (left and right sides).
[0037]
7A and 7B are diagrams showing the configuration of the slide member 80 disposed on the left side of the holder 56, where FIG. 7A is a front view, FIG. 7B is a plan view, FIG. 7C is a rear view, and FIG. (E) is a bottom view.
As shown in FIGS. 7A to 7E, the slide member 80 includes a sliding portion 80a formed in a U-shape and sliding on the top plate 74a, and both ends of the sliding portion 80a in the sliding direction. It has extension parts 80b and 80c which extend and are prevented from coming off from the top plate 74a, and a spring latching part 80d on which one end of the torsion spring 82 is latched. Further, on the lower surface of the sliding portion 80a, there are a pair of guide pins 80e and 80f, a contact portion 80g that contacts the insertion side end portions 36a and 46a of the recording media 36 and 46, and a pair of guide pins 80e and 80f. An engaging portion 80h formed in a trapezoidal shape at an intermediate position and a pressing portion 80i for pressing the media insertion detection switch 78 on the opposite side of the contact portion 80g protrude.
[0038]
Since the pair of guide pins 80e and 80f are fitted into inclined grooves 74e and 74f (shown by broken lines in FIG. 4) formed in the top plate 74a, the contact portion 80g is an end portion on the insertion side of the recording media 36 and 46. When pressed in the insertion direction (A direction) by 36a, 46a, it moves inward along the inclined grooves 74e, 74f. As a result, the slide member 80 moves in the direction approaching the side surface of the recording media 36 and 46, and the engaging portion 80 h engages with the concave portions 44 and 54 for clamping.
[0039]
Further, the slide member 80 moves in the insertion direction (A direction), and the slide member 80 clamps the recording media 36 and 46 from the side, and the pressing portion 80i comes into contact with the section of the media insertion detection switch 78 and turns on. Switch to state.
[0040]
Note that the slide member 81 is formed in a symmetrical shape with the slide member 80, and is different only in that the pressing portion 80i is not provided. Therefore, description of other common parts is omitted. In addition, the slide members 80 and 81 have the engagement portions 80h and 81h displaced inside the guide walls 58a and 59a of the guide members 58 and 59 and fitted into the clamp recesses 44 and 54, whereby the guide walls 58a and 59a. The restriction in the insertion direction due to is released, and sliding in the A direction becomes possible.
[0041]
Accordingly, in the process of inserting the recording media 36, 46 into the holder 56, the slide members 80, 81 move in the directions approaching each other while moving in the insertion direction, so that the engaging portion 80h is moved from both sides of the recording media 36, 46. The recording media 36 and 46 are clamped from both sides by engaging with the concave portions 44 and 54 for clamping.
[0042]
Here, the configuration of the holder driving mechanism 60 will be described.
FIG. 8 is a plan view showing the holder driving mechanism 60 partially enlarged. FIG. 9 is a side view of the holder driving mechanism 60 as viewed from the left side.
[0043]
As shown in FIGS. 8 and 9, the holder driving mechanism 60 includes a motor 86 disposed on the left side of the rear portion of the chassis 12 and a transmission mechanism 88 that transmits the rotational driving force from the motor 86 to the holder 56. ing. The transmission mechanism 88 includes a worm 90 fitted to the rotation shaft of the motor 86, a worm wheel 91 meshing with the worm 90, a reduction gear group 96 having a plurality of reduction gears 92 to 95, and an output side of the reduction gear group 96. And a rack 100 with which a pinion 98 is engaged.
[0044]
The rack 100 is fixed to the left side surface of the holder 56 and extends in the A and B directions. Therefore, when the rotational driving force of the motor 86 is transmitted to the pinion 98 via the transmission mechanism 88, the holder 56 moves in the A and B directions together with the rack 100.
[0045]
The gear 95 that meshes with the pinion 98 is supported so as to be slidable in the axial direction of the shaft 102, and is urged to a meshing position by a coil spring 104 wound around the shaft 102. The gear 95 biased by the coil spring 104 constitutes a mesh release mechanism, can move to the mesh release position against the spring force of the coil spring 104, and releases the mesh relationship with the pinion 98. The pinion 98 can be switched to the free state.
[0046]
That is, even when a power supply circuit trouble (for example, power failure, insufficient battery capacity, etc.) occurs due to the media being mounted and the motor 86 cannot be driven, by sliding the gear 95 to the mesh release position, the holder 56 is moved in the media discharge direction ( (B direction) can be moved.
[0047]
Here, the configuration of the opening / closing mechanism 62 that opens and closes the lid member 26 will be described.
FIG. 10 is a side view of the opening / closing mechanism 62 viewed from the side.
[0048]
As shown in FIGS. 10 and 8, the opening / closing mechanism 62 includes a crank member 106 that is pressed by an inclined cam portion 100 b provided at an end portion of a vertical wall 100 a formed integrally with the rack 100, and the crank member 106. The bracket 108 is rotatably supported, the torsion spring 110 biases the crank member 106 in the clockwise direction, and the open / close arm 112 connected to the eccentric pin 106a of the crank member 106.
[0049]
An end of the opening / closing arm 112 is rotatably connected to a pin 26d protruding from the left side surface of the flap 26a of the lid member 26. The crank member 106 is provided in the movement path of the vertical wall 100a and has a cam portion 106b that is pressed against the vertical wall 100a. When the holder 56 is in the mounting position, the cam portion 106b is spaced apart from the inclined cam portion 100b and rotates clockwise to drive the lid member 26 to the closed position. 60, the lid member 26 is driven to the open position by sliding in contact with the vertical wall 100a until it moves in the A direction to the position immediately before the mounting position.
[0050]
Further, the vertical wall 100a is provided with a recessed portion 100c that is recessed so as to rotate the cam portion 106b in the clockwise direction when the holder 56 stands by at an initial position where the media 56 is inserted and ejected. An inclined cam portion 100d that is continuously formed between the concave portion 100c and the vertical wall 100a is provided.
[0051]
That is, the lid member 26 is driven in the opening or closing direction in the process in which the cam portion 106b is in sliding contact with the inclined cam portions 100b and 100d, and is held in the open position while the cam portion 106b is in sliding contact with the vertical wall 100a.
[0052]
Further, when the holder 56 stands by at the initial position where the medium is inserted and ejected, the cam portion 106b is rotated in the clockwise direction because the cam portion 106b is inserted into the recess 100c. However, when the recording media 36 and 46 are inserted from the insertion slot 20, the lid member 26 is rotated clockwise, and this operation is transmitted to the crank member 106 via the opening / closing arm 112, and the crank member 106 is moved to the torsion spring. It is allowed to rotate counterclockwise against the spring force of 104.
[0053]
Therefore, the lid member 26 is driven to open and close by the opening / closing mechanism 62, but the opening / closing mechanism 62 is configured to be able to operate from the closed position to the opening direction regardless of the position of the holder 56.
[0054]
Here, a medium loading operation of the recording medium driving apparatus 10 configured as described above will be described.
FIG. 11 is a plan view for explaining the media insertion operation. FIG. 12 is a side view for explaining the media insertion operation. In FIG. 11, the cover 14 is removed, and in FIG. 12, the chassis 12 and the cover 14 are omitted.
[0055]
As shown in FIGS. 11 and 12, when the small recording medium 46 is inserted into the insertion slot 20, the insertion side end 46 a of the recording medium 46 presses the lid member 26 in the opening direction and enters the inside of the holder 56. . In the recording medium 46, guide portions 75d and 75e protruding from the inner walls of the side plates 75b and 75c are fitted into the guide grooves 52 on the left and right side surfaces, and the insertion direction and height position are guided.
[0056]
Further, when the recording medium 46 is inserted into the holder 56 in the A direction, the contact portions 80g and 81g of the slide members 80 and 81 provided on the top plate 74a of the holder 56 are pressed in the insertion direction (A direction). The When the holder 56 is in the initial position, the slide members 80 and 81 are biased outward (in the unlocking direction) by the torsion springs 82 and 83, respectively, so that the engaging portions 80h and 81h are guided by the guide member 58. , 59 are fitted in notches 58b, 59b (see FIG. 16 because they are hidden behind the top plate 74a in FIG. 11) and are opened in the left-right direction.
[0057]
FIGS. 13A and 13B are plan views showing a state before the slide members 80 and 81 are operated. 14A and 14B are plan views showing a state after the clamping operation of the slide members 80 and 81. In FIGS. 13B and 14B, the holder 56 and the torsion springs 82 and 83 are omitted.
As shown in FIGS. 13A and 13B, the slide members 80 and 81 are formed in inclined grooves 74e and 74f (shown by broken lines in FIG. 4) in which a pair of guide pins 80e and 80f are formed in the top plate 74a. It is mated. Therefore, when the recording medium 46 is pressed in the same direction as the recording medium 46 is inserted in the insertion direction (A direction), the slide members 80 and 81 move inward along the inclined grooves 74e and 74f.
[0058]
As shown in FIGS. 14A and 14B, the slide members 80 and 81 slide in a direction of 20 degrees obliquely with respect to the insertion direction (A direction) and approach the side surface of the recording medium 46 from the left and right sides. By moving in the direction, the engaging portions 80h and 81h engage with the clamping recess 54. Thus, the recording medium 46 is clamped so as to be sandwiched between the slide members 80 and 81 from both sides, and the clamping recess 54 is locked by the engaging portions 80h and 81h. Therefore, the recording medium 46 is held by the holder 56 by the clamping operation of the clamping mechanisms 76 and 77.
[0059]
Note that the slide members 80 and 81 are in sliding contact with the guide walls 58a and 59a of the guide members 58 and 59 in a state where the engaging portions 80h and 81h are fitted in the clamping recess 54. Therefore, the slide members 80 and 81 are urged outward (in the unlocking direction) by the torsion springs 82 and 83, respectively. However, while the holder 56 moves from the clamp position to the insertion direction and reaches the mounting position, It is held in a clamped state displaced inward.
[0060]
FIG. 15 is a plan view showing a state in which the recording medium 46 is inserted into the holder 56.
As shown in FIG. 15, when the recording medium 46 is inserted into the holder 56 and inserted into the clamping position where it is clamped from both sides by the slide members 80, 81, the pressing portion 80 i of the slide member 80 is moved to the media insertion detection switch 78. Switch to the on state by abutting on the slice.
[0061]
Therefore, the control circuit 72 activates the motor 86 of the holder driving mechanism 60 to move the holder 56 in the A direction as will be described later. The rotational driving force of the motor 86 is transmitted to the rack 100 through the worm 90, the worm wheel 91, the plurality of reduction gears 92 to 95, and the pinion 98. Then, the holder 56 configured integrally with the rack 100 conveys the recording medium 46 in the A direction while being clamped.
[0062]
FIG. 16 is a plan view showing a state in which the holder 56 and the recording medium 46 have arrived at the mounting position. FIG. 17 is an enlarged plan view showing the detection operations of the holder detection switch 68 and the attachment detection switch 70.
As shown in FIGS. 16 and 17, when the holder 56 arrives at a position immediately before the mounting position by driving the holder driving mechanism 60, the rear end portion of the rack 100 presses the section of the holder detection switch 68 to turn it on. . Further, when the holder 56 moves in the insertion direction and reaches the mounting position, the insertion side end 46a of the recording medium 46 presses the section of the mounting detection switch 70 to turn it on.
[0063]
As a result, the control circuit 72 stops the rotation of the motor 86 of the holder driving mechanism 60. In this way, the connector 50 provided at the insertion side end 46 a of the recording medium 46 is connected to the medium connector 64 provided on the substrate 66 in the process in which the holder 56 arrives at the mounting position. As a result, the recording medium 46 can write or read data via the media connector 64.
[0064]
Here, the ejection operation when the recording medium 46 loaded as described above is ejected will be described.
In the ejecting operation, when the eject button 73 of the front panel 16 is pressed and the eject switch 73 is turned on, the rotor (not shown) of the motor 86 is rotationally driven in the reverse direction during the mounting operation, and the holder 56 Is moved in the discharge direction (direction B), and the recording medium 46 is discharged to the insertion port 20. Then, the holder 56 is returned to the initial position (shown in FIG. 11), and the slide members 80 and 81 have the engaging portions 80h and 81h cut away from the guide members 58 and 59 by the spring force of the torsion springs 82 and 83, respectively. It moves to the clamp release position which fits 58b, 59b (refer FIG. 16).
[0065]
Thus, the recording medium 46 inserted in the holder 56 can be pulled out in the eject direction.
[0066]
18A and 18B are diagrams showing an opening / closing operation of the opening / closing mechanism 62, where FIG. 18A is a side view showing a mounting state in which the lid member 26 is closed, and FIG. 18B is a side view showing a process of opening operation accompanying the start of ejection. (C) is a side view showing a state in which the lid member 26 is opened, (D) is a side view showing a state in which the holder 56 is returned to the initial position, and (E) is a side view showing a state in which the recording medium 46 is pulled out from the holder 56. FIG. 4F is a side view showing a state in which the recording medium 46 is pulled out from the insertion slot 20.
[0067]
As shown in FIG. 18 (A), when the holder 56 is in the mounting position, the lid member 26 closes the insertion port 20 to prevent dust from entering the inside from the periphery. As described above, when the eject switch 73 is turned on and the motor 86 is rotationally driven in the reverse direction during the mounting operation, the holder 56 moves in the discharge direction (B direction).
[0068]
As shown in FIG. 18B, the inclined cam portion 100b of the vertical wall 100a provided integrally with the holder 56 as the holder 56 moves from the mounting position (see FIG. 16) in the discharging direction (B direction). The crank member 106 is slidably contacted with the cam portion 106b of the crank member 106 and is rotated counterclockwise. As a result, the open / close arm 112 connected to the crank member 106 is displaced in the A direction to rotate the lid member 26 in the opening direction.
[0069]
As shown in FIG. 18C, when the holder 56 is moved to the initial position (see FIG. 15), the upper end of the vertical wall 100a is in sliding contact with the cam portion 106b of the crank member 106 to further rotate the crank member 106 counterclockwise. Turn to. As a result, the open / close arm 112 connected to the crank member 106 is further displaced in the A direction to rotate the lid member 26 to the fully open position. At this time, the lid member 26 is held at the open position retracted upward from the path through which the recording medium 46 passes.
[0070]
18D, immediately before the holder 56 arrives at the initial position, the slide members 80 and 81 have the engaging portions 80h and 81h guided by the guide members 58 and 59 by the spring force of the torsion springs 82 and 83, respectively. It moves to the clamp release position which fits into the notches 58b and 59b (see FIG. 16). As a result, the engaging portions 80h, 81h of the slide members 80, 81 are displaced to the left and right sides so that the slide members 80, 81 are disengaged from the clamping recess 54 and release the locking (clamping) with respect to the recording medium 46.
[0071]
As shown in FIG. 18E, the recording medium 46 conveyed in the discharge direction by the holder 56 is pushed out in the discharge direction (B direction) by the clamp releasing operation by the slide members 80 and 81 as described above. It moves to a position protruding from the insertion port 20.
[0072]
At this time, the cam portion 106b of the crank member 106 passes through the vertical wall 100a and the inclined cam portion 100d and is above the concave portion 100c, but the lid member 26 is slidably contacted with the upper surface of the recording medium 46 and held in the open position. ing.
[0073]
As shown in FIG. 18F, when the recording medium 46 is pulled out from the insertion slot 20, the crank member 106 is rotated clockwise by the spring force of the torsion spring 110, and the opening / closing arm 112 is moved in the B direction. The lid member 26 is rotated in the closing direction (counterclockwise). Thereby, the insertion opening 20 is closed by the lid member 26.
[0074]
In this manner, the opening / closing mechanism 62 rotates the lid member 26 in the opening direction or the closing direction in conjunction with the movement of the holder 56, so that the insertion operation or the ejection operation of the recording medium 46 is not hindered. It is comprised so that it may drive.
[0075]
Here, the mounting operation when the recording medium 36 having a depth dimension larger than that of the recording medium 46 is mounted will be described.
FIG. 19 is a plan view showing a state in which the recording medium 36 is inserted into the holder 56. FIG. 20 is a plan view showing a state in which the recording medium 36 is clamped in the holder 56. FIG. 21 is a plan view showing a state in which the recording medium 36 is mounted together with the holder 56.
[0076]
As shown in FIG. 19, when the recording medium 36 is inserted into the holder 56, the insertion side end 36 a of the recording medium 36 presses the lid member 26 in the opening direction and enters the holder 56. In the recording medium 36, the guide portions 75d and 75e protruding from the inner walls of the side plates 75b and 75c are fitted into the guide grooves 42 on the left and right side surfaces in the same manner as the small recording medium 46 described above, and the insertion direction and height position are guided. .
[0077]
Further, when the recording medium 36 is inserted into the holder 56 in the A direction, the contact portions 80g and 81g of the slide members 80 and 81 provided on the top plate 74a of the holder 56 are pressed in the insertion direction (A direction). The
[0078]
As shown in FIG. 20, the recording medium 36 is inserted into the holder 56 to reach the clamping position, and the slide members 80 and 81 clamp the recording medium 36 from both sides. Then, the pressing portion 80 i of the slide member 80 abuts on the section of the media insertion detection switch 78 and switches to the on state.
[0079]
Therefore, the control circuit 72 activates the motor 86 of the holder driving mechanism 60 to move the holder 56 in the A direction. As a result, the holder 56 transports the recording medium 46 in the A direction while being clamped.
[0080]
As shown in FIG. 21, when the holder 56 arrives at a position immediately before the mounting position by driving the holder driving mechanism 60, the rear end portion of the rack 100 presses the section of the holder detection switch 68 to turn it on. Further, when the holder 56 moves in the insertion direction and reaches the mounting position, the insertion side end 36a of the recording medium 36 presses the section of the mounting detection switch 70 to turn it on.
[0081]
As a result, the control circuit 72 stops the rotation of the motor 86 of the holder driving mechanism 60. In this way, the connector 40 provided at the insertion side end 36 a of the recording medium 36 is connected to the medium connector 64 provided on the substrate 66 in the process in which the holder 56 arrives at the mounting position.
[0082]
The recording medium 36 thus mounted stops at a position where the discharge side end 36b is fitted in the insertion port 20 and the insertion port 20 is closed. Therefore, when the recording medium 36 having a long depth is attached, the lid member 26 is slidably contacted with the upper surface of the recording medium 36 and is held at the open position (see FIG. 18E).
[0083]
Further, in the ejection operation, similarly to the case of the recording medium 46 described above, the holder 56 is moved in the discharging direction by the reverse rotation driving of the motor 86 and the recording medium 36 is discharged from the insertion port 20.
[0084]
Here, the emergency operation for moving the holder 56 in the discharging direction by manual operation when the motor 86 cannot be driven due to a trouble in the power supply circuit (for example, power failure, battery capacity shortage, etc.) and the holder 56 cannot be ejected. Will be described.
FIG. 22 is a view showing the configuration of the emergency tool, where (A) is a plan view, (B) is a side view, and (C) is a front view.
[0085]
As shown in FIGS. 22A to 22C, the emergency tool 120 is made of a metal made of an aluminum alloy or the like, and extends in the axial direction from the grip portion 120a that is gripped by the operator and the grip portion 120a. And an insertion portion 120b.
[0086]
The insertion portion 120b has a cross-sectional shape that corresponds to the emergency hole 24 of the front panel 16, and a guide rail 79 having a U-shaped cross-section attached to the top wall of the cover 14 (see FIG. 6). A first flange 120c that engages with the first flange 120c, a guide groove 120d that is provided below the first flange 120c and extends in the longitudinal direction, and a second flange 120e that protrudes below the guide groove 120d. And a rack 120f that protrudes downward from the second flange 120e and extends in the longitudinal direction.
[0087]
The rack 120f is guided to a height position where it engages with the pinion 98 of the holder drive mechanism 60 by engaging the first flange 120c with a guide rail (not shown) provided on the inner wall of the top plate of the cover 14. It is burned. Therefore, when the emergency tool 120 is inserted into the apparatus through the emergency hole 24 of the front panel 16, the rack 120 f can be engaged from the upper side of the pinion 98.
[0088]
In addition, the insertion portion 120b of the emergency tool 120 has an insertion-side end portion 120g formed narrow, and an inclined portion 120h is provided at the insertion-side end portions of the first flange portion 120c and the second flange portion 120e. ing. The inclined portion 120h releases the meshing by pressing the reduction gear 95 meshing with the lower side of the pinion 98 to the left side. The reduction gear 95 is supported so as to be slidable in the axial direction of the shaft 102 and is biased rightward by the coil spring 104 to constitute a mesh release mechanism.
[0089]
Therefore, in the process of inserting the emergency tool 120 in the insertion direction (direction A), the inclined portion 120 h slides the reduction gear 95 to the left side against the spring force of the coil spring 104 to separate it from the pinion 98. Thereby, the holder 56 having the pinion 98 and the rack 100 is not restricted by the holder driving mechanism 60 and is switched to a free state.
[0090]
Therefore, after the reduction gear 95 is slid to the left side by the operation of inserting the emergency tool 120 to release the meshing relationship with the pinion 98, the emergency tool 120 is further inserted, whereby the rack 120f is moved to the pinion 98. In order to mesh, the holder 56 can be moved in the discharge direction.
[0091]
Here, an operation method and an ejecting operation in which the holder 56 that has become inoperable at the mounting position using the emergency tool 120 is moved in the discharging direction by manual operation will be described with reference to FIGS.
FIG. 23 is a view showing a state in which the emergency tool 120 is inserted from the emergency hole 24 of the front panel 16, wherein (A) is a plan view and (B) is a side view. 24A and 24B are diagrams showing an operation process in which the holder 56 moves in the discharging direction by inserting the emergency tool 120, where FIG. 24A is a plan view and FIG. 24B is a side view. 25A and 25B are views showing a state in which the holder 56 is returned to the initial position by inserting the emergency tool 120. FIG. 25A is a plan view and FIG. 25B is a side view. 26A to 26E are plan views showing the meshing release operation of the reduction gear 95 and the movement direction of the holder 56 that accompany the insertion / extraction of the emergency tool 120.
[0092]
As shown in FIGS. 23A and 23B and FIGS. 26A and 26B, when the insertion portion 120b of the emergency tool 120 is inserted from the emergency hole 24 of the front panel 16, the first portion 120b of the insertion portion 120b is inserted. The hook portion 120c is engaged with a guide rail 79 (see FIG. 6) provided on the inner wall of the top plate of the cover 14 to guide the insertion position.
[0093]
At the same time, an inclined portion 120h provided at the end of the insertion portion 120b slides on the reduction gear 95 to slide the reduction gear 95 leftward (C direction). As a result, the reduction gear 95 is separated from the pinion 98 and disengaged from the pinion 98.
[0094]
Therefore, the drive path by the reduction gear group 96 of the holder drive mechanism 60 is divided, and the restriction by the holder drive mechanism 60 on the holder 56 is released.
[0095]
As shown in FIGS. 24A, 24B, and 26C, when the emergency tool 120 is further inserted in the A direction, the rack 120f of the insertion portion 120b meshes with the pinion 98, and the pinion 98 is engaged. Rotate counterclockwise. Accordingly, the pinion 98 moves the rack 100 provided on the left side surface of the holder 56 in the discharge direction (B direction).
[0096]
Further, the holder 56 moves from the mounting position in the ejection direction, and the connector 50 provided at the insertion side end 46 a of the recording medium 46 is separated from the medium connector 64 provided on the substrate 66.
[0097]
Further, the lid member 26 is rotated in the opening direction by the opening / closing mechanism 62 described above in conjunction with the movement of the holder 56 from the mounting position in the discharging direction (see FIGS. 18B to 18E).
[0098]
As shown in FIGS. 25A, 25B, and 26D, when the emergency tool 120 is further inserted in the direction A, the holder 56 returns to the initial position, and the discharge side of the recording medium 46 The end protrudes from the insertion port 20.
[0099]
At the same time, the slide members 80 and 81 of the clamp mechanisms 76 and 77 described above operate in the open state opened in the left-right direction, and the clamps by the clamp mechanisms 76 and 77 are released. Thus, the recording medium 46 can be taken out from the holder 56.
[0100]
Thereafter, the operator pulls out the emergency tool 120 in the B direction as shown in FIG. When the emergency tool 120 is pulled out in the B direction, the pinion 98 rotates in the clockwise direction. Thereby, the holder 56 moves in the opposite direction (A direction) to the above and returns to the mounting position again. The reduction gear 95 slides in the D direction by the spring force of the coil spring 104 and meshes with the pinion 98 while the emergency tool 120 is pulled out in the B direction.
[0101]
As described above, the holder 56 can be ejected relatively easily by a manual operation using the emergency tool 120, and it is not necessary to arrange a plurality of levers inside the apparatus. It becomes possible to cope with space.
[0102]
When the control circuit 72 ejects the holder 56 by manual operation using the emergency tool 120, after the trouble of the power circuit (for example, power failure, insufficient battery capacity, etc.) is resolved, the control circuit 72 initializes the holder 56. A control process for returning to the position is executed.
[0103]
FIG. 27 is a flowchart for explaining a control process executed by the control circuit 72 after the emergency operation. The control process 72 executes the process shown in FIG. 27 at predetermined time intervals.
As shown in FIG. 27, the control circuit 72 checks whether or not the holder detection switch 68 is on in step S31 (hereinafter, “step” is omitted). If the holder detection switch 68 is OFF in S31, the holder 56 is not present at the mounting position, and the current process is terminated.
[0104]
If the holder detection switch 68 is on in S31, it is determined that the holder 56 is present at the mounting position, and the process proceeds to S32 to check whether the mounting detection switch 70 is turned off. In S32, when the attachment detection switch 70 is on, the recording media 36 and 46 are attached, and the current process is terminated.
[0105]
In S32, when the mounting detection switch 70 is off, the holder 56 has moved to the mounting position with the recording media 36 and 46 not inserted, so the process proceeds to S33 and the motor 86 is reversed. Polarity energization is started and the motor 86 is rotationally driven in the reverse direction during the mounting operation. Subsequently, in S34, the voltage applied to the motor 86 is lowered to set the rotational speed of the motor 86 to a low speed.
[0106]
The reverse rotation driving force of the motor 86 is transmitted to the rack 100 via the worm 90, the worm wheel 91, the plurality of reduction gears 92 to 95, and the pinion 98. The holder 56 having the rack 100 moves at a low speed in the discharge direction while the recording media 36 and 46 are clamped.
[0107]
In next S35, it is checked whether or not the holder detection switch 68 is OFF. When the holder 56 at the mounting position starts to move in the discharge direction by the holder driving mechanism 60, the holder detection switch 68 is switched off with the rear end portion of the rack 100 being separated. Therefore, at 35, when the holder detection switch 68 is turned off, it is determined that the holder 56 has moved in the ejection direction from the mounting position and the connectors 40, 50 of the recording media 36, 46 have been separated from the media connector 64. In step S36, the voltage applied to the motor 86 is increased to switch the rotational speed of the motor 86 to high speed rotation.
[0108]
Thereby, the ejection speed of the holder 56 is switched to a high speed. In next S37, it is checked whether or not a predetermined time set in advance has elapsed. The holder 56 moves to the initial position while a predetermined time elapses. In S37, when a predetermined time has elapsed, the process proceeds to S38, in which the energization of the motor 86 is turned off and the rotational drive of the motor 86 is stopped.
[0109]
As a result, when the recording media 36 and 46 are removed by manual operation using the emergency tool 120, the holder 56 can be automatically returned to the initial position. In the flowchart of FIG. 27, when the holder detection switch 68 is on and the attachment detection switch 70 is off, the motor 86 is rotationally driven in the reverse direction during the attachment operation to move the holder 56 to the initial position. However, the present invention is not limited to this. For example, when the holder 56 into which the recording media 36 and 46 are not inserted is not in the initial position, the holder 56 is moved to the initial position by driving the motor 86. Also good.
[0110]
In the above-described embodiment, the case where the second recording medium 46 is removed by manual operation using the emergency tool 120 has been described. However, the first recording medium 36 is attached and a power supply circuit trouble (for example, power failure) Of course, when the motor 86 cannot be driven due to insufficient battery capacity or the like, it can be taken out by manual operation as described above.
[0111]
In the above-described embodiment, the recording medium driving device to which the recording media 36 and 46 are mounted is described as an example. However, the present invention is not limited to this, and the present invention is also applied to a device to which a recording medium having a shape other than the above is mounted. Of course, the invention can be applied.
